Interesting image Rob.
I haven't tried to image it through red or IR filters so don't know how red it is. It is pretty bright in blue on my images with a B-V of about 0.7.
I compared your image to mine. The image scale is amazingly different. Your image is west up and north to the left compared to my north up. The bright blurry star next to the "x" on your magnified image is the NGC 3603 that is on the edge of my field. My image is slightly smaller than your magnified part.
